STITCH SEPARATING AND INDENTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,601, dated April26, 1904.

Application filed June 13, 1903. Serial No- 161,332. (No model.)

To all 10720172, it ma n concern.-

Be it known thatwe, FREDERICK J. THON and HARRY G. WOLF, citizens of theUnited States, and residents of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have made a certain new anduseful Invention in Stitch Separating and Indenting Machines; and wedeclare the followingto be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention, referencebeing had to theaccompanying drawings, and to letters and figures of reference markedthereon, which form apart of this specification.

Figure l is a side elevation of the invention. Fig. 3 is a detail Viewshowing the gearing adapted for hand-power. Fig. 4; is a detail view, ona larger scale, of the two stitch-indenting rollers and theirbearing-boxes and showing the antifriction-roller d. Fig. 5 is a detailView showing the upper toothed roller and its bearing-box in plan view.'Fig. 6 is a detail view showing the cam d upon the lower shaft andantifriction-roller upon the upper shaft in side View. Fig. 7 is adetail view showing the formation of the front standard to allow theremoval of the bearing-boxes therein. Fig. 8 is a sectional detailview'showing the pivotal connection of the upper rear bearingbox withthe standard.

This invention has relation to stitch separating and indenting machinesfor the soles of boots and shoes, and has for its object the provisionof an efiicient machine for this purpose of simple and comparativelyinexpensive character, which will be applicable to any form of work andwhich may be dismantled without taking the main frame apart.

With this object in view the invention consists in the novelconstruction and combinations of parts, all as hereinafter described,and

pointed out in the appended claim.

Referring to the accompanying drawings, the letter A designates the mainframe of the machine, which is designed to be mountedupon a table andconsists of two parallel standards A, connected by longitudinal bracesa, the standards having feet screwed to base A B B are upper and lowerparallel shafts situated closely together and rotatably mounted inbearing-boxes b, fitting in guideways b of the standards of the mainframe and carrying the upper toothed wheel 0 and the lower feed-rollerG, having a smooth periphery, said wheels coacting upon the ShOGrSOlGfor the end in view. In order to provide for separation of these twowheels G and C in inserting and removing the work from between the same,the rear bearing-box of the upper shaft is pivotally mounted in theframe, two transverse removable screw-bolts c entering seats 0 of saidbox and upon which the shaft turns as it is raised by the actionofcam-lever D, pivotally mounted upon the lower shaft B close by theforward standard A and having a cam-head 0Z working against anantifrictionroller 61 upon theupper shaft. A spiral spring Z, locatedbetween the top of the guideway of the forward standard and the upperforward bearing-box, and controlled in pressure by the screw Y, exertspressure to force the two wheels G and 0 together.

-The bearing-boxes b are provided with lateral grooves bounded by endflanges 6 these boxes, which,with their shafts, are removable from thestandards,being inserted in the guideways ?2 at their enlarged upperportions 6 and being lowered enter the contracted lower portions of theguideways, so that their end flanges will embrace the side walls of theguideways and the boxes be firmlyheld in place. The upper boxes 5 havethe inner walls of their end flanges inclined or oblique, as shown atb", to admit of pivotal movement thereof without binding against thestandards. The upper boxes '6 rest upon the lower bearing-boxes.

Referring now to the means for rotating the shafts, 1 l are small twinintermeshing spur gear -wheels mounted upon shafts B B and located justinside of the rear standard A, a large spur-gear 2 being carried by thelower of said shafts just outside of the rear standard and meshing withpinion 3 of spur-gear 4, said pinion and gear 4 having a removable boltcon nection with the main frame at 4c. The spurgear 4 meshes withspurgear 5 on shaft 6, carrying driving-pulley 7, a friction-clutch 8being utilized to set the driving-pulley in motion through pedalconnection 9.

The shaft 6 and its connections are mounted in detachable frame 10,bolted to the base A at 11 and to the rear standard at 12, the inner endof shaft 6 being removably seated in the rear standard at 6. By removingthe bolts at 11 and 12 the frame 10 may be removed,with shaft 6,driving-pulley, frictionclutch, and spur-gear 5, for the purpose ofconverting the machine into a hand-operated device, a gear 13 with crankattachment 14 having its shaft inserted in seat 6 in lieu of gear 5.

The upper toothed indenting-wheel C is secured to its shaft by means ofscrews a passing through a collar 0 of said shaft. The lower wheel C isremovable for the purpose of substituting a longer or shorter wheel foroperating upon work having open or closed channels. The upper forwardbearing-box has forwardlyprojecting flanges c laterally perforated forthe attachment of the guard X.

By means of the transverse cam-lever D working close by the forwardstandard power is applied to separate wheels 0 U in a direct andpositive manner, and inasmuch as only the shaft and its bearingboxes areraised a compartively slight power will accomplish it.

By means of the intermeshing spur gears 1 1, located upon the parallelshafts inside of the rear standard, the power for rotation of saidshafts is applied in adirect manner, avoiding any lost motion, the twoshafts being driven at the same rate of speed,which is most essentialfor the ends in view.

A pedal connection R may be provided for the transverse cam-lever D.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

In a stitch separating and indenting machine, the combination of theparallel standards having the guideways, the lower removablebearingboxes in said guideways, the upper removable bearing boxes insaid guideways resting upon the lower bearing-boxes, the upper and lowerparallel shafts in said bearingboxes situated closely together, thestitch-indenting and feed wheels upon said shafts, the uniformintermeshing spur gear-wheels upon said shafts, and a transversecam-lever pivoted upon the lower shaft, and adapted to engage the uppershaft to raise the same, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
